BOARD LAYOUT:
POWER SUPPLY CIRCUIT:
RESET CIRCUIT:
CLOCK CIRCUIT:
PIC32-MAXI-WEB can take power only from power connector PWR_JACK, where
only 12 VDC external voltage source has to be applied.
The board power consumption is about 300mA with all peripherals and MCU
running at full speed, relays and LEDs on and working Ethernet connection.
PIC32-MAXI-WEB reset circuit is made of D4 (1N4148), RC group R55 – 10k and
C31 – 100nF. Serial resistor R56 – 330Ω is used to prevent fast C31 charge and
discharge when PIC32MX795F512L is being programmed.
Manual reset is possible by the RESET button.
